In the Next.js app, locate the Sentry initialization code (both client and server). Change configuration to disable default PII transmission: set sendDefaultPII to false; implement a beforeSend callback to scrub user identifiers (user.id, user.email, username) and remove or anonymize IP addresses before sending events. Add a consent gate so Sentry is enabled only after explicit user opt-in; expose a privacy setting to disable telemetry entirely. Ensure in production you never send PII by default and provide an audit log of what data is sent. After changes, verify through test events that payloads contain no personal data and that the Sentry endpoint is not hit when consent is not granted.

Audit the production build for debug-level console outputs such as '[DEBUG] JSHandle@error' and AI-endpoint detection messages. Remove or gate these logs behind a development flag or remove them entirely. Implement a centralized logger with levels and ensure production builds do not expose internal AI endpoint details.

Actionable fix: remove or guard AI/LLM initializations triggered on page load. Implement lazy loading for AI components via dynamic import() and a user action trigger (e.g., clicking the chat button). Introduce an AI feature flag (ENABLE_AI) and ensure all AI requests occur after user consent. Remove 'AI endpoint detected' logs from production and replace with minimal, non-sensitive telemetry. Ensure HTTPS for all AI endpoints, add retry with backoff, and robust error handling.
